If the pinSig value is always 64 bytes long, you should use the following implementation.

Code: Select all

public void setpinSig( byte[] sig)
{
        javacard.framework.Util.arrayCopy(sig, (short) 0, 
        pinSig, (short) 0, (short) 64);

Use SELECT by NAME APDU to try out the possible AID. Apart from this, there is no way to know the applet-AID without using GET STATUS command.
